Module unit 

The run unit: every program a run calls, sharing one memory as they share an address space on z/OS. A called program keeps its WORKING-STORAGE and open files from one CALL to the next until it is cancelled. A reference or pointer can reach anywhere in this memory, but never outside it.

Structs

Library

Where CALL finds programs: the other programs of the first program’s source, then program libraries searched by member name.

Enums

Clock

Event

What a run did that its evidence journal records: each file as it is opened and closed, and each program CALL loads, with the source it was read from when a library supplied it.

LoadError

Constants

ADDRESS_BASE

A pointer’s value is its offset into run-unit memory plus this, so that no item’s address is NULL.

MAX_DEPTH

How deep PERFORMs and CALLs may nest before the run abends, rather than exhaust the stack.

RETURN_CODE

RETURN-CODE, a halfword shared by every program in the run unit.
